depend on cycle rate.
2. I
CC1
, I

depend on output loading. Specified values are obtained with the output open.
3. Address can be changed once or less while RAS = V
IL
. In the case of I
CC4
, it can be changed once or less when CAS = V
IH
.
4. When refreshing both banks at once, the refresh current becomes 2160mA.
